Network Standards:
Ethernet V1.0/2.0 IEEE 802.3: 10BASE-T, 10BASE5. (Magnum Personal Hubs are physical layer standard Ethernet products, and operate in networks independently of all software.)
Operating Environment:
Ambient Temperature:32ºF to 122ºF (0ºC to 50ºC) Storage Temperature:-20ºC to 60ºC
Ambient Relative Humidity:10% to 95% (non-condensing)
Power Supply (External) (H80B, optional for H80P):
Power Input: 95 - 125 vac at 60 Hz for "-d" Models, 200 - 250 vac at 50 Hz for "-i" Models, which have IEC power cable connector in the external power unit.
Power Consumption: 10 watts max
Connectors:
H80B: 8 front-mounted shielded RJ-45 (1 with up-link switch), 1 rear BNC with internal termination switch.
H80P: 8 front-mounted shielded RJ-45, 1 rear DTE (male AUI)
(Shielded 10BASE-T connectors accept either unshielded or shielded wiring lugs for standard twisted pair media wiring.)
The regular RJ-45 ports support the standard for hubs-to-users twisted pair wiring: pin 1= receive+, 2 = receive-, 3 = transmit+, 6 = transmit-, other pins not used. The RJ-45 port with the MDI-X switch is normally the same, but when switched it supports the standard for up-links using twisted pair wiring, i.e., the transmit and the receive pairs are exchanged: pin 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive- , other pins not used.

Switches:
Up-Link: MDI-X (Media Dependent Interface - Crossover) manual slide switch, converts RJ-45 port #8 from a regular (=) user segment port to a crossover (X) up-link port for on-off connection to a backbone or another cascaded hub.
Internal Termination (H80B only): Allows BNC conneciton without use of "T" connector. Right position -- internal termination, no "T" required. Left position -- external termination via "T" connector required.

Magnum H80B and H80P Personal Hubs User Guide (07/95)
2.2Product Description
The Magnum H80B and H80P Personal Hubs are nine-port workplace hubs in a very compact package. They are simple to install and use in an office or lab environment, requiring no special rack cabinets or wiring closet apparatus. Personal Hubs are standard physical layer Ethernet products and operate independently of all software.
Personal Hubs fit easily into the workplace environment. They are versatile enough to be table-top or shelf-mounted. Alternatively, a Velcro strip is included in the package so that the unit may easily be installed on a wall surface, or on the back or side of a desk or cabinet. All of the wiring connectors are in the same plane so that wiring space is neat and minimal. The external power supply unit (optional for the H80P) conveniently plugs into an AC wall receptacle or power strip.
The H80B and H80P Personal Hubs' RJ-45 ports support connection of up eight workstations or other network devices over full length 10BASE-T cable segments. Personal Hubs operate in compliance with the IEEE 802.3 specification for repeater functionality to perform signal amplification, re-timing of data packets, and regeneration of preamble bits for each packet received.

Magnum H80B and H80P Personal Hubs User Guide (07/95)
Consistent with IEEE 802.3 specifications, Personal Hubs will detect collisions, extend collision fragments, and automatically partition and re-connect individual ports in order to keep problems on one segment from causing downtime elsewhere on the network.
Personal Hubs include LINK and RX LEDs, located on top of the unit above each RJ-45 port, and one LED for DC power located at the rear near the external power supply connection. For observing operational information from the LEDs, it is easy to associate the status LEDs for each of the ports with the appropriate port plug.
2.2.1Magnum H80B Product Description
Magnum H80B Personal Hubs provide a simple and inexpensive solution for networking a personal multi-system office using 10BASE-T twisted pair cabling. They are perfect for sites that have ThinNet installed and need to wire additional office space for twisted pair.
Magnum H80Bs are also well suited for small- to-medium- size office or lab environments (up to eight persons) that need an independent Ethernet network. They operate as self-sufficient units
